BRAKE-ACTU'ATING MECHANISIVI.

Application filed June 19, 1911. Serial No. 634,023.

To all 'whom 'it may] concern: l

Be it known that l, CHARLES A. LIND- sTRM, a citizen of the United States, residing at No. 138 Stratford avenue, Pittsburgh, in the county of Allegheny and Stateof Pennsylvania, `have invented certain new and useful Improvements in Brake-Actuating Mechanism, of which the following is a specification, `reference beinghad to the accompanying drawings, which form a part` of the specification.

My invention relates to improvements in .brake actuating mechanism and particularly to such mechanism as is actuated by a hand brake-lever as described-and claimed in my United States Patents No. 571,134.9, granted January 5th, 1897, and No. 578,573, granted March 9th, 1897.

The objects attained by my present invention are as follows: 1 theassembling of the principal component parts withoutl the use otl bolts, rivets, keysk or threaded parts; 2, the prevention of theft or malicious removal of the hand brake-lever; 3, the simplification of the mechanism, reduction of number and cost of parts and consequent cheapening of cost of manufacture, application and maintenanceyil, the `fastening of the lower ratchet wheel to the shaft by suitably shaped portions `obtained by making themast in two parts; 5, the employment of means for automatically returning` the hand brake-lever to its inoperative position; 6, the location of they automatic returning means in a position in which it willbe protected from the weather and from being tampered with or accidentally injured.

The nature of my improvements will be best understood as described in connection with the drawings in which they are illustrated and in which Figure 1 is plan viewshowing the bearing member in which the upper end of the brake mast is supported, and the mechanism and brake lever connected with the upper end of the brake mast, Fig. 2 is a longitudinal section on line A-A of Fig. 1, of the bearing member, brake lever mechanism and left-hand end o' the brake lever, the right-hand end oi" the brake lever being shown in elevation. Fig. 3 is a section on line B-B of Fig. 1; Fig. -1 is a section on line C-C of Fig. 2; Fig. 5 is a section on line D-D of Fig. 2; Fig. 6 is a section .onI

Referring: to Figs. 1 toI 12 of the drawings,` 1 is a rotatable brake mast such as is commonly vused in a railroad or street car.r

` Itl is provided with a bearing member shown in Fig;V 8, near its upper end, said bearing member being preferably formed of two pieces, 2 and 3. The lower portion 4 ofthe bearing piece 2 is so formed that it iitsmore ,or` less loosely into a Lcorresponding recess 5 in' bearing piece- 3, and is'provided with projecting portions 6 which fit into corresponding recesses in piece 3, thus preventing any appreciable movementof'piece 2 relative to f piece 8. Thevupper-portion'ofbearing-piece 2 is so formedas to overlap the upper portion of bearing piece 8, said overlap extend ing to a point corresponding vwith the center line ofthe brake mast. rl`he uppermost' portions of the parts 2- and 3 'are in formv ofnan annular recess 7, half of the yrecess being formed oneach' piece, Figs-9 andv 10, and forming when fitted together-the complete annular recess as shown in Fig. 8. This an nular recess 'isformed with iat and angular surface as shown' in- Fig. 2, but may be made offany suitable shape, and adapted to retain, in a freely rotatable position, the portion 8 ofi the end of the brake lever. Piece 2 is `also provided with a stop lug as indicated at 7', the purpose of which will be hereinafter explained. The two pieces 2 and 8' of the bearing member, Fig. 8 are held in normal position relative to each other by means A which pass through holes 9, 9, in the flanges 1010'ofthe piece 3, and which serve to secure the complete bearing member against thel end of the car, the end 11 ofthe piece 2, being in the same vertical plane as the outer face offthe flanges,and lalso bearing against theend of the car. Assh'own, the upper end vof the brake mast lfis square as indicated at 12 and may be provided with acylindrical mast.

clutch".- 1G is a hub ofthe brake lever, the

lower portion 8 being formed to the annular recess '7 formed 1n the bearing member, in such a manner as to admit of free rotation. The upper part of the hub-16, is

chambered, as indicated at 17, so as tosurround the ratchet` wheel 14, and as indicated at 17 to surround the end 13 ofthe brake I 18 is a'brake lever extending out from the hub 16,/ 19 being a slot formed through the walls of the chamber 17, in line with 'the lever 18. 20 isl a lug depending from the under'V side of the lever 18 and 21 istlie handle of the lever. 15 is a pawl having-a beveled front edge as shown, said' pawl e'Xtendingl through the slot 19l and being secured tol theleve-r 18, so aste move angulari;7 with said leverand. `atthe same ltime free vto `taire a longitudinal 'motion independent ofthe lever which will permit vtov engage ordisengage; with the ratchet 14.V lInthe construction shown the motion of the pawly 15 is'in-a straight line, the pawl being coupled by asjoint 23 with the rod 24, which again is coupled by a pin 25 withthe lever 26, 27, the end of which is'pivoted at 28 to the lever 18, while the end v27 extends out in a direction approximately parallel to the lever 18, lying-in such a position to the hand grip ofthe lever that they can both be read-l grasped at the same time. A spring 29 is also provided through which rod 24 passes, the'action of which is to thrust the pawl into'engageme'nt with4 the ratchet wlieel'14, one endof `the spring resting against the pawl 15I 'and the other end againstlug 20, substantiallyas describedA in one of my United States patents hereinbefore referredfto'viz: No.-574,549.l The hub end ofthe bralelever'is provided with a projecting s top-l'ug'84,l which is adapted to contact 'with'the stopflug" 7 on the bearing member, and so-limit theeXtent of rotation of the hub` 16 ofthe brake lever 18. The lower end 35 of the brake mast 1', isk squared and inserted in a square holein the ratchet wheel 36, and the end '37 of the extension brake mast 88 is also squared, and is inserted in the same hole in the ratchet wheel 86, the ends of the two shafts substantially meeting at a point about midway of the length of the hole inl the ratchetk wheel. From' lthe vforegoing description, it lwill be understood that no bolts, threadedv parts, keys or pins are used to hold'the brake lever on thebrale mast, the ratchet tothe mast, or the bralrel mast and the ratchet wheel together, the' only securing means used being,y the bolts'passing through the holes in the4 flanges of the bearing member which! are for the purpose of securing `this member tothe l Referring now to Figs. 13 to 18 of the drawings which represent some modifications in the form of the details of myinvention, and in which like reference characters indicate like parts in Figs. 1 to l2. The hub 16 of the brake lever is, in this modified form, extended downwardly at 39, and provided with a recess into which the hooked end of a spiral spring 41, made of material of fiat or other suitable section, is inserted and secured. rlhe bearing members Figs. 1T and 1S aremade sufficiently large and provided with a recess 'l' to receive and contain one or more coils of the spring 41, the outer end of the spring being secured in any suitable manner to one of the portions of the bearing member. The object of the spring is to exert sufficient turning power on the hub of the brake lever, to cause the handle of the brake lever to be automatically returned against the end of the car and to remain there until moved away from it by the operator.` 'j

Figs. 28 and 29, show another method of applying a springsimilar to that just described in which the spring is located entirely outside the bearing member 2, 3, and the brake lever, and in which the inner end ofthe spring is attached to the upwardly projecting portion 17 of the hub of the brake leven The outer end of the spring of my United States patents hereinbeforey referred to, viz No. 578,573. y

In Figs. 19 to 23, l show al further modification of my invention which is especially applicable to passenger'cars, and in which like reference characters indicatey like parts in Figs. 1 to 12. The formation of the parts of the bearing member shown in Figs. 22

and 23, being such as would be easily applied and secured to the end construction of a passenger carwith vestibuled platform. The method of securing together the two parts 2, 3, ofthe bearing member, and `of securing them to the end of the car differs in detail from that shown in the aforementioned figures. The part 2 is provided with a straight portion 50 and flange 51, and part 3 with corresponding straight portion 52l and flange 53, which, when the two parts y2 and 3 are assembled, are brought together as shown in Fig. 19, and secured together by the same bolt, passing through flanges 51 and 53, as secures this side of the bearing` member tothe end of the car. At the .other side ofthe bearing member, the parts2 and 3 are furnished with anges 54 and 55, which as shown in'Fig. 19 are brought together and so secured by bolt 'or other suitable means. Part 2 is also furnished with another flange 56, for the purpose of forming an` additional means for securing the cat'e'like parts in F igs.` 1 to 12, and 13 to A1.6,

it will readily be 'seenthat in orderl ytoiremove the brake lever it'is necessary to remove the bolts which secure the whole mechanism to the car, which can not readily be done without `proper tools, thus preventing thefts of `levers which have been frequent when the levers are made of expensive material such as bronze; onthe other hand, levers are very seldom removed for, repairs or other causes, so that the increased difli#V culty of removal is onlyv slight compared with the advantages gained, whichl advantages also include the removal of the twov parts of the brake mast, ratchet and ratchet wheel, by the removal of the same bolts only.

Fig. 26 illustrates a further modification of a spring means which may be utilized for retaining the outer end of the brake lever in close proximity to the end of the car,

and consists in a helical spring 43, one end of which is secured to a suitable projection or lug near to the hub end of thebrake lever, the other end being secured to a bracket 44 or other suitable means attached to the end of the car as shown in the figure or to a suitable projection on the portion of the bearing member 2, and while as hereinbefore stated, externally located means for returning the lever to inoperative position are not preferred, yet when used they should be lo-` cated as near thecenter of the hub as possible to obtainwell known advantages iin construction.

It will be readily observed -that in all the modifications, the action and function of the parts described is substantially the same. The operator, taking hold of the hand-grip 21, moves the lever through "a portion of an arc, turning the shaft 1, which is engaged and held against a backward motion by the pawl 22 and ratchet wheel 36, so that in place of setting the brakes by one continuous movement, the operator can work the lever 18 like the handle of a pump, and have at the same time thepawl 15 always' under control of the same. hand which grasps the hand-grip of the lever.
